About this Mod

 

Magicians are widely known as powerful wielders of magic.
In truth, however, they rely on summoned spirit slaves, known as demons, who perform magic on their behalf.

This mod is inspired by the world of Jonathan Stroud's Bartimaeus. If you haven't read the books, do that now!
With the help of occult rituals you will summon spirits, also known as demons, from "The Other Place" to aid you in your adventures.

A ritual magic system centered around summonable spirits allows you to automate various tasks, store vast amounts of items, let demons mine in void dimensions, create powerful enchanted tools and jewelry, get support from familiars, and much much more.

Begin your journey by crafting the Dictionary of Spirits, and following that in-game guide, discover the secrets of the spirit world,
find otherworld groves hidden in plain sight by gaining the "Third Eye", and finally summon your first spirit.  

 

See Screenshots for some impressions.
